FRUIT-JAR.

SPECIFICATION forming part of Letters Patent No. 723,017, dated March 17, 1903i.

-Application filed June 13, 1902.

To @ZZ whom it may coiwe'nli Be it known that I, EDMUND A. PARKER, a citizen of the United States, residing at Meriden,county ofNew Haven, State of Connecticut, have invented a new and useful Fruit- .Iar, of which the following is a specification.

My invention relates to jars forputting up fruit, vegetables, dac., and has for its object to provide a jar of this character which shall be simple and inexpensive to produce, in which the contents do not come in contact with either metal or rubber,`but only with glass or porcelain, which may be illed entirely full, may be easily closed, will be absolutely air-tight, and maybe readily opened without the use of tools or opening devices of any kind and by a lady, as the operation is the simplest possible and requires very little strength, the operator having the advantage of a wide grasping-flange upon the top, which overhangs the threaded retaining-ring.

With 'these and other objects in View the invention consists in certain constructions and in certain parts, improvements, and combinations, which will be hereinafter described and then specifically pointed out in the claims hereunto appended.

In the accompanying drawing, forming part of this specification, the figure is a view, partlyin elevation and partlyin section, illustrating the construction and operation of my novel fruit-jar.

l0 denotes the body of the jar, and 11 the neck, lwhich is provided with an external screw-thread'12, with a circular ledge or shoulder 13, and which may or may not be provided with an upwardly-extending circular flange 14.

15 denotes the cover or top, ordinarily lnade of glass or porcelain, which is provided with an external screw-thread corresponding with the thread on the neck, with a grasping-ilange 16, which is of greater diameter and o'ver hangs the threaded portion, and with a depression 17, having a raised hub or boss 18. This hub or boss is provided with an opening 19 through it and with an external screwthread 20, which is engaged by a cap 21, having a packing 22 of cork in the bottom thereof. The manner in which the hub and central opening are made isof course not of the serial No. 111,497. (No man.)

the outer face of the hub until the opening is reached and is of the required size. I have shown the top or cover as provided with a circular groove 23, which receives the edge of flange 14, so that the cover, in fact, extends down within the neck slightly-thatis,slightly below the top of the flange, as at; 24.. This groove and depending portion 24, as well as the flange 14 upon the neck, are not, however, essential features of the invention.

25 denotes a continuous-threaded metal ring adapted to be engaged by the threads 12 on the neck and top.

26 denotes a gasket or packing-washer interposed between ledge or shoulder 13 and the top.

The operation is as follows: In filling, the jar should be filled full, a gasket placed upon the shoulder, and the cap removed from the hub on the top. The threaded ringis turned down upon the neck, and then the top is screwed down into the ring, or vice versa, as preferred. Having made the top tight upon the jar, the contents will of course rise and fill opening 19 inthe hub. Cap 21 is then turned to place, the cork in the bottom of the cap insuringa perfectly tight connection with the top of the hub, which has a ground surface. It will thus be seen that the jar is entirely lled and if the work is properly done will be absolutely without air-space, thereby insuring perfect preservation of the contents and Without possibility of the contents coming in contact with either metal or rubber. In opening, the operator may, if preferred, unscrew the cap first, which admits air into the jar and makes it much easier to unscrew the top. In practice, however, I iind that it is ordinarily not necessary to remove the cap, as the wide grasping-ilange upon the top gives to the operator such a purchase as to make IOC it comparatively easy to turn the top in the threaded ring and Without requiring the exercise of very much strength.

Having thus described my invention, I claim- 1. In a fruit-jar the combination with an externally-threaded neck and a top havinga corresponding external thread, of a continuously-threaded ring adapted to engage the threads upon the neck and the top.

2. In a fruit-jar the combination With an externally-threaded neck and a cover having a corresponding external thread and a grasping-ange overhanging the threaded portion, of a continuously-threaded ring adapted to engage the threads upon the neck and the top.

3. In a fruit-jar the combination with an externally-threaded neck and a cover having a corresponding external thread, a depression and a threaded hub in the depression having an opening, of a cap adapted to close the opening and a continuously-threaded ring adapted to engage the threads on the neck and top.

4. In a fruit-jar the combination with an externally-threaded neck having a shoulder and a 'lange 14,' and a top having a corresponding external thread and a groove to receive the flange leaving the central portion of the top depending within the neck, of a continously-threaded ring adapted to engage the threads upon the neck and the top.

5. In a fruit-jar the combination with an externally-threaded neck and a continuouslythreaded ring, of a top having an external thread also adapted to engage the ring and a grasping-liange upon the top which overhangs the threaded ring.

6. In a fruit-jar the combinationwith an externally-threaded neck and a continuouslythreaded ring, of a top having an' external thread also adapted to engage the ring, a depressed portion, a threaded hub having an opening through it and rising above the depressed portion and a threaded cap adapted to engage the hub to close the opening.

In testimony whereof I affix my signature in presence of two Witnesses.

EDMUND A. PARKER.
